Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If beam-related reference signals are transmitted using a shared resource pool, then resource allocation flexibility is improved, but power fluctuations occur leading to degraded signal quality
Solution Approach 1:
The patent segments the resource pool into two distinct types: dedicated resource pools for beam-related reference signals and shared resource pools for other transmissions. This segmentation prevents beam RS transmissions from causing power fluctuations in shared resources, thereby maintaining signal quality while preserving resource allocation flexibility for non-beam purposes.
Solution Approach 2:
The patent applies local quality by providing different resource pool configurations for different transmission purposes. Dedicated resource pools are specifically configured for beam management with appropriate power control parameters, while shared resource pools are optimized for other transmissions. This localized optimization ensures each resource pool has the appropriate characteristics for its intended use.
2Quantity of substance
If beam-related reference signals are transmitted using a shared resource pool, then resource utilization is improved, but resource allocation efficiency is reduced
Solution Approach 1:
By dividing resources into dedicated and shared pools, the system ensures efficient allocation: dedicated pools guarantee resources for beam management without competing for shared resources, while shared pools remain available for other transmissions. This segmentation eliminates resource contention and improves overall allocation efficiency.
Solution Approach 2:
The dedicated resource pool acts as an intermediary that handles beam management transmissions separately, preventing them from interfering with shared resource allocations. This intermediary structure allows the system to maintain high resource utilization while avoiding the inefficiencies of mixed-purpose resource sharing.
3Adaptability or versatility
If beam-related reference signals are transmitted using a shared resource pool, then resource flexibility is improved, but power levels become unstable
Solution Approach 1:
The patent segments transmissions by purpose, placing beam-related reference signals in dedicated resource pools with controlled power levels. This separation prevents beam RS power variations from affecting shared resource power stability, maintaining stable power levels in shared pools while preserving flexibility in dedicated pools.
Solution Approach 2:
Different power control mechanisms are applied locally to each resource pool type. Dedicated resource pools use power control optimized for beam management, allowing flexibility when needed. Shared resource pools use power control mechanisms that prioritize stability, ensuring consistent power levels for general transmissions.

AI summary
Provided are a method for a first device to communicate wirelessly and a device for supporting same. The method may comprise the steps of: acquiring information related to a dedicated resource pool; acquiring information related to a shared resource pool; transmitting, to a second device, at least one reference signal (RS) related to at least one beam; and selecting a first beam on the basis of a first RS of the at least one RS. For example, the first RS may be transmitted to the second device on the basis of the dedicated resource pool, and the first RS and data may be transmitted to the second device on the basis of the shared resource pool.
